This invention relates to a card having a sound producing device carriedthereby; and the object of this invention is to mount a sound producingdevice between the different plies or thicknesses ofsheet stock formingthe card in such position that it may be i operated by blowing air atthe edge of the card.

A still further object of'the invention is to provide a picture mailingcard with a 'twotone sound producing device between the plies orthicknesses of stock at its edge to be operated by the mouth of the userwith openings in one of the plies of stock dlsposed inwardly from itsedge for permitting the escape of air after-passing through the soundproducing device.

With these and other objects in view, the invention consistsof certain.novel features of construction, as will be more fully described, and.particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of a postcard showing the sound producingdevice in the form of a harmonica mounted along one of its edges.

Figure 2 is an elevation showing the back of the card. 7

Figure '8 is a perspective harmonica.

Figure 4 is a perspective view of the frame used in mounting theharmonica between plies of sheet stock forming the card.

view of the Figures 5 and 6 are perspective views of the guard formed ofmoisture-resisting material to be mounted on the back and front of thecard adjacent the edge which is received in the mouth for protecting thecard against moisture.

Figure 7 is a 77 of Figure 1.

Figure 8 is a perspective View of a modified construction of card andsound producing device mounted therein.

Figure 9 is a central section of the card fragmental section on lineshown in Figure 8.

It is found desirable in the making of picture cards for mailing orother purposes, to provide a sound producing device partially concealedbetween the plies or thicknesses of sheet stock forming the card andlocated in such position that the same may be operated by the mouth ofthe user, preferably a two or more tone sound producing device such as aharmonica or the like is 1927. Serial No. 185,439.

employed with a channel for conducting air to and from the soundproducing device and with a guard along the mouth engaging edge of thecard formed of tinfoil or other moisture-resisting material to protectthe card from softening by moisture from the mouth; and the following isa detailed description of the present embodiment of this inventionandshowing one means by which these advantageous'results maybeaccomplished:

With reference to the drawings, 10- desig nates the front and 11 therear ply of sheet material usually formed of paper or some similarmaterial, the plies being glued together along the edges. Suitablymounted between these different plies of sheet stock is a soundproducing device 12 shown in Figure 1 in the form of a harmonica 13 witha frame 14 positioned between the reedcarryingplate 15 of theharmonicaand the rear ply of sheet stock 11 to allow the reed to vibratein the space 16 within the frame.

1st and not be obstructed by the ply of sheet stock 11. In order thatthe air, which operates the reeds of the device by passing directly intothe harmonica when located along the edge, as shown in Figure 1 mayescape I have provided a series of openings 17 in the rear ply ofsheetstock 11 for this purpose.

In order that the moisture from the mouth in operating the soundproducing device or harmonica will not soften and injure soft papercard, I have mounted a moistureresisting guard 18 along the front and aguard.- 19 along the back of the card the latter being provided withsuitable openings 20 corresponding to the openings 17 in the back plateto permit the escape of air therethrough.

In some instances a different type of sound producing device such asthat shown at 21 in Figure 8, may be mounted within the different pliesof stock of the card which is the two tone whistle type, the air beingadmitted through the opening 22 at the edges of the plies of stock ofthe card to be conducted along a conduit 28 to the sound pro ducingdevice 21 and through the same to be discharged through openings 24 inthe rear ply of sheet stock. A guard 25 formed of single piece ofmoisture-resisting tinfoil or the like with an opening to correspondwith is provided to extend along the outer surfaces of the cardtoprotect the same against moisture from the mouth of the'user, also aguard strip 26 to strengthen the stock about the openings 24 is providedwith suitable openings 27 to register with openings 24 to permit escapetherethrough.

The front of the card may be suitably ornamented by a picture asillustrated at 28 and the rear card may be provided with a space 29 foraddressing for mailing purposes, if desired.

From the foregoing it will be seen that I have provided a simpleconstruction of device by which a sound producing device may be mountedin an ordinary nailing card to cause the same to be more attractive andcreate a different, additional and greater interest in the card to besent through the mail, it being understood that the sound producingdevice may be made of wood or other comparatively indestructiblematerial which will not be easily injured and yet will be sulficientlylight. to adapt it for the purpose desired.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanicalvchanges to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim: a

1. In combination with a picture card formed of a plurality of plies ofsheet stock, a sound producing device between the plies of stock locatedin a position to be operated by the mouth of the user.

2. A picture card formed of a pair of sheets of material securedtogether along their edges, a sound producing device mounted betweensaid sheets, said sheets being spaced apart to permit the entrance ofair to the sound producing device and one of said sheets having anopening to permit the escapeof air after passing through said soundproducing device.

3. A picture card formed of a plurality ot' plies of sheet stock with asound producing device between the plies located at the edges thereoffor access to the mouth of the user, and a guard along the edge of thecard adjacent the sound producing device to protect the same from themoisture of the mouth. 7

4. A card formedof a pair of sheets cured together along their edges asound producing device for. producing plurality of tones mounted betweensaid sheets along the edges thereof to receive air from the mouth of theuser, one of said sheet-s having a plurality of spaced openings topermit the esc pe of air after passing through the device, said openingshaving passageways communicating with differenttone portions the devicewhereby the tones may be controlled by obstructlon of the openings.

5. A cardformed of a plurality of plies of stock, a harmonica mountedbetween said plies at the edge of the card one of the plies of stock atone side of the cardhaving a plurality of openings to permit theescapeof air after passing through the harmonica,

and moisture-resisting material along the
